How do you calculate compound interest every 6 months?
If an account earns interest compounded every six months, the periodic interest rate per each six-month period is i = 12%/2 = 6%. If the account earns interest compounded quarterly, or four times a year, the periodic interest rate is i = 12%/4 = 3%. Many accounts earn interest each month, so i = r/12.
